Organization Consolidation And Presentation Of Financial Statements [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards – In May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update to provide guidance on the recognition of revenue from customers. Under this guidance, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. This guidance also requires more detailed disclosures to enable users of the financial statements to understand the nature, amount, timing and uncertainty, if any, of revenue and cash flows arising from contracts with customers. The requirements in this update are effective during interim and annual periods beginning after December 15, 2017. The Company adopted this new revenue guidance effective January 1, 2018, utilizing the modified retrospective method, and expanded its consolidated financial statement disclosures in order to comply with the update (See Note 3). The adoption of this update did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued an accounting standards update to provide guidance for the accounting for leasing transactions. The standard requires the lessee to recognize a lease liability along with a right-of-use asset for all leases with a term longer than one year. A lessee is permitted to make an accounting policy election by class of underlying asset to not recognize the lease liability and related right-of-use asset for leases with a term of one year or less. The provisions of this standard also apply to situations where the Company is the lessor and may require the Company to separately account for lease components from non-lease components within a contract. The Company will elect the practical expedient that allows the exclusion of leases with terms less than one year, as well as the practical expedient allowed to lessors to not separate the lease components when the non-lease component is the predominant component. The Company has selected a lease software platform, and is in the final stages of aggregating the information from its lease contracts into the lease software. The Company is also assessing and updating its procedures and controls to prepare for the changes resulting from the new guidance. The Company expects its assets and liabilities to increase as a result of recognizing the right-of-use assets and lease liabilities, but the Company does not expect a significant impact to its earnings or cash flows. The Company will adopt the new lease guidance effective January 1, 2019, utilizing the transition method that allows a retrospective approach through a cumulative-effect adjustment at the beginning of the period of adoption for current leases as of that date. Lease arrangements for the working interests from oil and gas properties are excluded from the scope of the new lease standard. The Company is continuing to evaluate the impact this new guidance will have on its consolidated financial statements. In August 2016, the FASB issued an accounting standards update to clarify the presentation of cash receipts and payments in specific situations on the statement of cash flows. The requirements in this update are effective during interim and annual periods in fiscal years beginning after December 15, 2017. The adoption of this update on January 1, 2018 did not have a material impact on the Company’s consolidated financial statements. In May 2017, the FASB issued an accounting standards update that provided clarity on which changes to the terms or conditions of share-based payment awards require an entity to apply modification accounting provisions. The requirements in this update are effective during interim and annual periods in fiscal years beginning after December 15, 2017. The adoption of this update on January 1, 2018 did not have a material impact on the Company’s consolidated financial statements. In March 2018, the FASB issued an accounting standards update to update the income tax accounting in U.S. GAAP to reflect the SEC interpretive guidance released on December 22, 2017, when significant U.S. tax law changes were enacted with the enactment of the Tax Cuts and Jobs Act (“Tax Reform”). The adoption of this update in March 2018 did not have a material impact on the Company’s consolidated financial statements, as the Company was already following the SEC guidance. See Note 12 for additional information. In August 2018, the FASB issued an accounting standards update to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments in the update are effective for public business entities for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact this new guidance will have on its consolidated financial statements.
